Appiicaaon' ala Apriti ze,

To all w/iom/ may conce/Mi.'

Be it known that l, THiioDoim Eeoi'som a citizen of theilnited States, residing at lolland, in the county of 'Ottawa and State oi liichigain have invented certain new and useful improvements in Roller-Bearing# Sleeve Fullers andl do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled iu the art to which it appertains to make and use thesame.

ln removingl roller bearing' sleeves from the ends of autoniobile axlehousings and the like, a great; deal of dii'iiculty is often experienced`v and it is the object of my inv` vention to provide an improved type of puller forsleeves of this character, by wliose' use, such sleeves may be quickly and easily re'nioved, the construction being preferably7 such that the sleeve maj.7 be withdrawn, either with theaxle extendingl through. said sleeve or with such axle removed.

lilith the foregoing in view, theS invention resides in' the novel subject mattei'` hereiiiaite'r described and claimed, the description heir' supplemented by the accompanyinig; drawings.` y

Figure l is a side elevation showing the bearing' sleeve of a'l rear automobile axle,

with the driven axle extendingv throughsaid' sleeve.

File/'ure 9. is a view similar to 1, but` illustrating the device 'in position for' with` drawingthe sleeve.

Figure 3 is a view similar to Fig. 2, but

showing the manner Ain which the device is employed to remove a sleeve after the' adjacent axle section has been withdrawn.

Figure 4 is a'n enlarged side elevation partlv in section. showing"` the portion of the. device which is insertible into the sleeve tobe removed;

Figure. 5 is a in 4.

Figure 6 is a perspective view of the sleeve pulling bar and the lateral arms with which it is provided. Y

Figure 7 is a perspective view of the sleeve-engaging member which is pivoted to the arms of the pullingbar.

Figure 8 is a perspective view of the actu ating; lever for the pulling bar.

In the drawings above briefly described.

the numeral l designates an elongated bar plan view of the parts shown seriaiirolvaeia whose front end is adapted to beinserted into a bearing' sleeve to be removed, said bai' being' provided with mea'n'srsiich asthe lug 2, to engage the sleeve, at one side of ther latter, said lug being` adaptedprimarily for reception in the usual opening' in" the side of the sleeve shown in" Figs. l7 E5' and 3. A sleeve-engaging member eX- tends laterally Yfrom the bari and is pivoteii to the latter' onJ an axis extendingr transverselythereot, said member 3 being adapted to swing'4 toward the bar as Shown in l, so that it mavfbe readilv inserted intoy the sleeve with said bar, Then, when" the lug Q'lias been engaged with the' sleeve pning", oi" anv other slee'veengaging' means with which said bar mayr be provided; is properly engaged with'lthe sleeveg the iiien'iber 3 .is adapted to swing outwardly away from they bar, to the position ilisclsed in Figs. 2 and 3. In this posi-i 'fio'iigv it abiits the sleeve and prevents lateral ii'icvement ot the bar l. ina direction which wo'iild permit said bar to disengage" the sleeve. rllliiis.` an outward pull on the bar, with sutcient torce, rwill withdraw' Ithe sleeves from its holding position.` Preferabljv',y sprii'ig means is associated with the bai" l andthe member 3, to outwardly swing the latter when the devic'eis'in proper positionw'itliiir the sleeve.l Y

In con,structinlirA and mountin`tlfie`member' 3. l prefer to emplov the details diseii. j. Ai of oppesiteiy extending" curved ai'nrlis l have been` shown projecting troii'ithe iront" portionof the l anddisposed in" a' commdn transverse plane,` the upper"v endsVl oi said arms" termi'natinpf` iu ears 5 whose rear edges are preferab'l'v spaced inwardlv from the rear edgfes of said armsly leaviii'g shoulders 6 at the upper rear corners oi said ai" The member 3 is shown ot" arched form and it mayA well be formed of a single piece of metal. the ends ot said member being` provided with outwardlv extending trunnions Z which are received in openings 8 formed in the ears 5. Behind these trunnions. the ends of the member 3 are provided with downwardly extending studs 9 for reception in the upper ends of coiled compression springs 10. and in front of the trunnions 7. the ends of the member 3 are provided with lateral stops 11 to abut the front edges of the arms 4, so as to limit the outward swinging,l

of said member away from the bar 1. In the construction shown, the springs 10 have their lower ends received in sockets 12, formed in the arms 4 and opening through the shoulders 6.

To insert the device, whether the axle remains within the bearing sleeve or has been previously removed therefrom, the member 3 is swung rearwardly against the action of the springs 1.() permitting the front end ofthe device to readily enter the sleeve, as shown in Fig. 1. As soon as the bar 1 is properly engaged with the sleeve, which in the present disclosure, necessitates reception of the lug` 2 in the sleeve opening, the springs 10 right the member 3 and it thus abuts the sleeve, so that the bar cannot move inwardly and disengage from said sleeve; Then, an outward pull upon the bar will withdraw the sleeve very easily.y

Any desired means may be employed for outwardly pulling upon the bar 1. I preter however to provide the outer portion of this bar with a plurality of teeth 13 to engage a tooth 14 on a hand lever 15, said lever having an opening 16. through which the bar 1 passes slidably. A fulcrum spur 17 has been shown on the lever 15 to engage the outer end ot a driven axle as shown in Fig. 2 so that rocking of the lever about said fulcrum spur will pull outwardly on the bar 1 and extract the bearing sleeve. This spur can only be used when the axle section remains in place. Hence, in order that the lever 15 may be used also when said axle section has been removed, a pivoted leg 1S is preferablyV provided on one end of the lever, which leg may be swung inwardly as shown in Fig. 3 and engaged with the end ot the axle housing or other` desired part. so that it may act as a fulcrum for the lever.

Excellent results Vare obtainable from the simple and inexpensive construction which hasbeen shown and described, and such construction is therefore preferably7 followed'` but within the scope ot the invention as clai1ned, numerous modifications may be made.

I claim:

LA roller bearing sleeve pulling device comprising a bar for insertion into a bearing sleeve, said bar having means to en'- gage the sleeve at one side of the latter, and a sleevelengaging'member insertible into the sleeve with and pivoted to said bar on an axis transverse to the latter, saidmember extending laterally from said bar and being adapted to swing toward the saine for insertion into said sleeve, said member being then adapted to swing outwardly from said bar and abut the sleeve to hold said bar in engagement therewith.

2. A structure as specified `in claim 1; together with spring means acting on said pivoted member and reacting on said bar for outwardly swinging the former when the device is in 1position in the bearing sleeve.

8. A roller bearing sleeve pulling device comprising a bar insertible into a bearing sleeve and provided with means to engage the sleeve at one side of the latter, said bar having a pair of lateral arms disposed in a common transverse plane and insertible into the bearing sleeve. and a curved sleeveengaging member pivoted to said arms on an axis transverse to the bar, said member being adapted to swing toward said bar when the device is being inserted into the sleeve and being then adapted to swing awav from said bar and abut the sleeve to hold the device engaged therewith.

4f. A structure as specified in claim 3; togather with spring means acting on said pivoted member and re-acting upon said bar to swing the former outwardly away :from said bar.

5. A roller bearing sleeve pulling device comprising a bar insertible into a bearing sleeve and provided with means to engage the sleeve at one side ot the latter, said bar having a pair of lateral arms disposed in a common transverse plane and insertible into the' bearing sleeve. a curved sleeve engaging member pivoted to said arms on an axis transverse to the bar. said member having spring-engaging studs at one side ot its pivotal axis and stops at the other. side of such axis, the latter being adapted to abut said arms and limiti the outward swingingof said 'member awafv vfrom 'the bar, and coiled compression springs thrust'- ing` at one end against portions ot said arms and at their other ends receiving said pin-engaging studs. whereby to swing said member outwardly to the limit allowed by said stops.

l'n testimonv whereof I have hereunto aHixed my signature.
